| 摘 要： | 真空断路器开断电机回路时 ,会产生截流过电压、多次重燃过电压及三相同时截流过电压。因此 ,在电机回路中装设真空断路器时 ,必须有完善的保护设备来限制真空断路器的操作过电压 ,以保护主设备 ,使电力系统安全、可靠、经济地运行。特别是在发电机回路中使用真空断路器时 ,更要慎重 ,除具有完善的保护措施外 ,还要考虑其绝缘水平配合、发电机回路的电容电流、切断直流分量的要求等因素 ,使真空断路器的优良性能得到充分发挥

| Abstract: | While the vacuum circuit breaker turns on/off the circuit of the motor, it can produce the cut-off over voltage, multiple reclose over voltage and 3-phase simultaneous cut-off over voltage. Therefore if the vacuum circuit breaker is equipped in the motor circuit, it is necessary to provide perfect protective device to limit the operating over voltage of the breaker to protect the main device and make the power system run under reliable, economic and safe conditions. Especially for vacuum circuit breakers used in the generator circuit, more attention must be paid to the following factors, like matching of insulation level, capacitor current in the generator circuit, requirement for cutting off the DC component in addition to the perfect protective measures. In this way the wonderful property of the breaker can be fully brought out. |
